In this study, indium–tin oxide (ITO)/Nb-doping TiO2 (TNO) double-layer transparent conductive (TCO) films deposited using DC magnetron sputtering were used as a surface anti-reflection layer with an overall thickness of 100 nm for films. The simulated results showed that ITO and TNO combinations 90 nm/10 nm, 80 nm/20 70 nm/30 had higher transmittance lower reflectance than others in the visibl...

Towards the demonstration of sub-10 nm III-V vertical fin and nanowire MOSFETs, a novel alcohol-based digital-etch technology has been developed. The new technique minimizes the mechanical forces exerted on vertical nanowire structures. A consistent 1 nm/cycle etching rate on both InGaAs and InGaSb-based heterostructures has been obtained. This is the first demonstration of digital etch on anti...

A rapid, simple and reproducible HPLC method was developed and validated for the analysis of nimodipine (NM) and/or its metabolite, oxidized nimodipine (OX-NM) in rat cerebrospinal fluid (CSF) and artificial CSF. The NM and OX-NM were eluted in less than 10 min with no interferences from the endogenous CSF peaks. Analysis was carried out on a Eurospher Performance (RP-C18, 250 × 4.6 mm) column ...

The scaling of transistors to sub-10 nm dimensions is strongly limited by their contact resistance (RC). Here we present a systematic study of scaling MoS2 devices and contacts with varying electrode metals and controlled deposition conditions, over a wide range of temperatures (80 to 500 K), carrier densities (10(12) to 10(13) cm(-2)), and contact dimensions (20 to 500 nm). We uncover that Au ...

OBJECTIVE To investigate the role of adrenoceptor subtypes in regulating the spontaneous contractile activity of the inner lining of the urinary bladder (urothelium/lamina propria). MATERIALS AND METHODS The responses of isolated strips of porcine urothelium/lamina propria to noradrenaline, phenylephrine, and isoprenaline were obtained in the absence and presence of receptor subtype-selective...

Ge/Si core/shell nanowires (NWs) are attractive and flexible building blocks for nanoelectronics ranging from field-effect transistors (FETs) to low-temperature quantum devices. Here we report the first studies of the size-dependent performance limits of Ge/Si NWFETs in the sub-100 nm channel length regime. Metallic nanoscale electrical contacts were made and used to define sub-100 nm Ge/Si cha...

BACKGROUND The prognostic significance of Karnofsky performance status in neoplastic meningitis (NM) has not been demonstrated in patient groups similarly matched for known prognostic variables. OBJECTIVE To determine the effect of performance status on survival in NM. DESIGN Retrospective comparison. SETTING A university tertiary medical center. PATIENTS Two well-matched cohorts with c...
